' SPECIFICATION forming part of Letters Patent No. 255,877, dated April 4, 1882. Appui-.Anon mea ombet 1s, 1881. (No maar To all whom @t may concern:

Be it known that I, LUPPE LUPPEN, a citizen of the United States, residing at Pekin, in thecounty of Tazewell and State of Illinois, haveinvented certain new and useful Improvements in Gultivators; and I do hereby de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and io the letters or figures of reference marked thereon, which form a part ofthis specification.

My invention relates to machines for cultivating corn and other crops; andthe object of my improvements is to provide certain novel combinations of devices for the purposes hereinafter described.

Figure l is a plan view of my improved cultivator. showing the construction and arrangement of its parts. i Fig. 2 is a sectional elevation, and Fig. 3 is a perspective view of some ofthe parts in detail.

Similar letters referto similar parts throughout the several views.

In constructing cultivators of this type there are provided two carrying-wheels, A A', which may be of any desired dimensions and of any approved construction. These wheels are mounted upon the arched'axle B, to which theyare secured by a pin or nut in the usual manner, but so as to turn freely thereon. This axle may be made ofa round or otherwise formed bar of metal, it `having upon itsV outer ends the required wheel-seats.

In making provision for drawing the implement forward there is placed upon its axle, at or near the point `where the vertical portions join the horizontal portions, clips C C, which are firmly secured thereto by set-screws or in any other suitable manner. lhese clips are provided with an aperture in the direction of the path of the implement, through which pass rods of metal C', which are held in position by the setscrews C2 G2. On the forward ends of the rods G spiral springs G3 C3 are placed, they being held thereon by pins or nuts. Resting upon the rods C', on either side of the axle9 are two arms, C4L C5, the opposite ends of which are attached to a sliding bar, G6, which is composed of two parallel plates of metal, as

shown in Fig. 2, in order that flanges which project from brackets D D secured upon the axle B, may pass between them, and thus form;-

guides for the sliding frames composed ot' the rods C,arms C* and G5, and bar C6 to slide upon. i

To the outer or forward arm, 05 there is attaehed one of a pair of` draw-bars,-E 11i/,fthel one lettered E being pivoted thereto in such a manner as to allow it to turn upon its pivotal point, the one-lettered Ebeing also secured to the arm C5, but provided with a slot at its inner end, as shown in Fig. l, in order that when theouter ends ofthe bars are joined to the clevis E2 they may form a pivotal point ,for it to turn upon,.and at the same time per- The elevis E2 above alluded to consistsota curved bar of metal, `the rear edge of which isi provided with a projection, as shown in Fig. `2, which enters the space between the bars E and E. The curved portion of this clevis extends above and below the point where it is joined to the draft-bar, and is provided with a seriesof holes for the attachment of the sin,- gle-trees in such a manner that by changing the positions thereof the shovels ot' the cultivater will be caused to enter the earth to a greater or less depth, according to the requirements of thecase and the quality of the soilas, it' the single-trees are attached to the cle"- ises below where they are connected to the draftbars, the shovels or plows will be caused to enter the earth to a greater depth than when they are attached at or above such point. It will be seen, therefore, that the form of clevis enables the operatorto regulate the depth to which the shovels shall enter the earth in all kinds of soil, or in cultivating all kinds of crops which are planted in rows sufticiently far apart to permit this kind of cultivation to be adopted.

The beams of the cultivator, which may be of any approved form, are attached to the rear" bars, C4, of the sliding frame, said bars being capable of revolving in their bearings; or the clamps F, which secure the plow-beams thereto, may be made to turn thereon, the object being IOO to make provision f'or the raising and lowering of the shovels or plows without changing the height of the point to which they are attached. The rear end of the clamp F is provided with two projecting ears, through which passes a bolt or pin,v which also passes through projections in bilureated blocks IT', which are attached to the forward ends of the plow-beams, the arrangement ot' these parts being such that the shovels or plows may be caused to run nearer to or farther from the rows of the crop. Each of the gangs ot' shovels or plows is provided with a handle, G, by which they maybe guided. 1

In providing` for preventing the axle B from being turned ont ot' its propery position, there are applied to the under sides of the brackets D D' arms H Hf, which extend rearward at a suitable angle to admit of there being attached to their' outer rndsbars of metal H2 H3, the lower rear ends ot' which are enlarged and allowed to rest upon the earth when the implement is being moved from field to field, or at other times, the effect of which is to prevent the weight of the shovels or plows from turning the axle out of position. The bars H2 H3, just alluded to, are pivoted to the arms H H in such a manner that their outer ends can be turned up,and thus removed from contact with the earthwhen desirable to do so, they being held in their operative positions by a slide movingon the arms H H.

For. the purpose otl holding the gangs of shovels or plows clear of the earth when the implement'is being transported from pla-ce to place, and when it is not desirable t0 have the shovels enter the earth, there are attached to the arms H H' bars of metal I I', which extend upward and rearward sucieutly far to allow the bent rear ends thereof to form restingplaces for the beams of the gangs, they being placed therein by the operator raising their rear ends and placing them in position.

It will be seen from the foregoing description and upon reference to the drawings that the implementdescribed and shown constitutes a tongueless cultivator-one which may be advanta geously used without such an appendage; but it is not .intended to limit the improvement to that type of implements, as the parts and their combinations are applicable to cultivators using tongues as well as to those not using them.

Having thusy described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a straddle-row cultivator, the combination of an arched axle, a sliding frame, to` which the forward ends of the beams are con# lsliding frame, the draw-bars E E', the forward ends ot' which vibrate laterally, and the pivoted clevis E2, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence ot' two witnesses.
